Key clinical point: Patients with atopic dermatitis (AD) treated with dupilumab have an increased risk for cutaneous T-cell lymphoma (CTCL) compared with those not treated with dupilumab.
Major finding: Patients with AD who did vs did not receive dupilumab had a significantly higher risk of developing CTCL (odds ratio [OR] 4.1003; 95% CI 2.055-8.192). The risk for CTCL persisted in those with no prior exposure to disease-modifying antirheumatic drugs (OR 3.202; 95% CI 1.573-6.514).
Study details: This retrospective cohort study included patients with AD who did (n = 22,888) or did not (n = 22,871) receive dupilumab treatment and did not have a preexisting diagnosis for CTCL, Hodgkin lymphoma, non-Hodgkin lymphoma, nonfollicular lymphoma, leukemia, malignant melanoma, squamous cell carcinoma, or basal cell carcinoma.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
